Tasks

• Write docs/SENSORS.md
• Delta hardware-kit sensor requirements
• SKU shopping is later (classes live in docs/SENSORS.md; /i glass preferred)
• Amend the design and delta so HSB/USB is explicitly an AGX bring-up fallback; the production body path remains enclosure-mounted CSI/GMSL into Thor NVENC.
• Amend the design and delta to separate the P-iris turret encode stub from the shipped satellite class, and specify the hardware path for Cooke-class lens metadata plus per-satellite UART ToF alongside edge-encoded PoE H.265.
